NON-SKID DEVICE.

T0 all w/mm 'it 'muy cfr/merit.'

Bc it known that l, S'rlvn Reines, a subject of the lhnlieror of Austria-Hungary, residing at East Youngstown, in the county of Mahoning and. State of tlhio, have in,- vented certain new and useful .linprovenients in NimeSkid Devices, of which' the following is a specification. rl`his invention .relates to certain new and useful improvements in ruin-skidding devices. 1

r1`he primary object of the device is to vprovide in connection with any form of traction wheel such as a pneumatic tired automobile wheel, an attachment having calk spikes shftahle into and ont of engagingr position with the road bed and operable at will by the driver of the vehicle.

A further object of the device is to provide shiftable lallis radially 'arranged around a traction wheel and automatically projected successively as theyreach their downwardly-extending vpositions` upon the turning of the wheel and whereby certain ones of said calks engage the road leed to prevent skidding and side slipping of-the wheel as well as increasingthe road-traction qual ies thereof.

A stillfurther object is to provide av pl'urality of radially shiftahle calk spikes arranged around a wheel and norinally ont of contacting exuragen'lent with the road bed but capable of manipulation at the will of the drix'er so that each onesuccessively becomes projected upon reaching its lowermost position and thereby engageahle with the roadi'bed.

lVilh these general objectsv in View and others that will appear as the nature of the invention better understood, the saine consistsin the novel combination and arrangement of parts hereinafter fully described, illustrated in the accon'nnulying drawings, and pointed out in the appended claims.

In the drawings forming a part of this` application and in which like designating characters refer to corresponding parts throughout the several views: Figure 1 is 'an elevation of the inner side of a wheel i Specification of Letters Patent.

Application filed March 30, 1914. Serial No. 828,237.

vertical central section, and, Fig. 5 is a perspective view of the shiftable wedge. Referring inorein detail to the drawings, the wheel 1() is illustrated having an aXle 11 and an o1itwardly-extending hub 12. A plurality of radially-arranged rods 13 are slidablysinounted. through perforations 14 in an' outer annulus 15 Vsecured adjacent to the wheel felly while the projecting ends 16 of said rods are screw-threaded for receiving removable calks 17 thereon and adapted to be normally positioned inwardly'ofthe tread surface of the wheel tire so as not to engage the road bed. A band 18 is provided with open slots 19, each slot thereof adapted to receive one of the rods 13 therein for positioning said rods in their sliding movements, -Collars 19 secured upon said rods position encircling springs` 20 between the saine and the inner periphery of the annulus l5, whereby the rods are normally projectved inwardly with their base plates'21 slidahly seated upon the outer periphery of a collar 22 and within a groove 22.v thereof u and which is secured in a stationary position against revolution in any desired manner by a connection vwith the vehicle, as by means of the bracket 23 which may be secured to the axle housing, the lower leaf of the automobile spring7 orother fixed part of the vehicle. One side 'of the collar 22 is cut-away providing a seat 23 upon which is slidahly-mounted the shiftable wedge 24 having an inclined or tapered arcuate inner edge 25. Said 'wedge is at all times positioned en the lower side of the collar 22 and tlnrcfore engageable by the bases 21 of the rods and the rods successively move across the saine during the rotation of the wheel. With the .vedge positioned at the limit of its inox einent inwardly as shown in Fig. L1, the rods are moved. outwardly upon contactin o' the saine and thereby projecting the calles 17 of the lowerinost rods in to contact with the road bed while with the wedge 2l outwardly })ositicncd, the edge thereof performs no function in its contact with the rods to project the saine. The wedge 21 is provided with an arcuate rih 2G adapted to limit the outward movementol' the wedggge by cooling in contact with the annular :band 27 positioned at the outer edge of the collar 22 while such band is provided with an inner notch Q8 for slidably receiving the transverse rib 29 or" the shiftable wedge, and thereby' guiding the wedge in its sliding movement. Y

It being desirable to place the shiftable wedge into and out of its operative position lor actuating the rods, the said wedge is provided with a bolt 30 connected by a linlz 3l with a rocker arm and actuated by means of an operating rod 35:5 extending to a convenient point to be reached by the dri ver of the vehicle while the arm SZbcing pivoted to a bracket Bil upon the collar 2% provides a structure in which a downward thrust of the rod 33 withdraws outwardly the shi'ftahle wedge 2l while an upward pull upon said rod'forces said wedge inwardly for contacting?j engagement with the successively aprroachinar rods 13. f

lilith this detailed description. ofthe deviceT the complete operation thereof will be apparent in that when desired to utilizo the non-skid calks 17, the lever -33 is pulled upwardly. for shifting the wedge Q4 inwardly to the position shown in Fig'. 4; and whereby its inner edge Q5 is engaged successively by the rods upon a turningA of the wheel and the lower ones of said rods are outwardly projected thereby. The rods and calks are normally held inactive by the resilient nienr bers Q0 and 'in which position the ealks will not engage the road bed while the wedge is retracted bv a downward movement ofthe operating lever. J

While the forms of the invention herein shown and described are what: are believed to be nreferable embodiments thereof, it is nevertheless to he' understood `that various forms and inodiications thereof may be had vwith out deoartinp; from the spirit and scope of 'the invention as claimed.

llVhat claim as new iszi. The combination with a wheelandaxle, of a stationary collar withinwhieh-siid axle rotates` an annulus secured to the wheel and provideil with radial periorations` radial rods slidahly positioned within said .perforations and having'their inner ends resilientlv andsiidably seatedupon the outer periphery of said collar; a band having,r slots to receive said rodsfoneside of said collar being71 formed with a lseat., 'a wedge slidably mounted within said seat and having an inmodena clined inner edge adapted for engagement with 'the inner ends of certain of said rods9 and means for-shifting said wedge.

. 2. ,ln combination with a wheel and 4axle, a non-rotating collar upon said axle, an annulus concentric with said hub and pro vided with radial perforations, one side of said collar being formed with a seat, a wedge slidably mounted within said. seat and having;v an inner tapered edge, rods radially arranged through the perorations of said. annulus and having their outer'ends screw-threaded and projecting outwardly of the annulus, springs carried by said rods and normally nositioninr the inner ends or said rods slidably upon said collar and wedge during a rotation of the wheel, and removable calks upon said rod ends.

8. The combination with a wheel and axle, of a stationary collar within which said axle rotates having a scatter-med on one side thereof and an annular peripheral groove, an annulus secured to the wheel'iand pro vided with radial periiovr'ations, radial rods slidably nositioned within said neriiorations and having* their inner ends resiliently and slidablv positioned in said groove. a wedge slidable axiallv within said seat and having an inclined edge adanted for engage ment with the inner ends of certain oi said rods,

and means for shifting said wedge.
